In 1944 people in Saskatoon called a meeting to discuss the formation of a senior citizens club. Many towns were represented including Moose Jaw. The Old Age Pensioners Club was formed with Mrs. A. Douglas, president; Mrs. Nurse, secretary; and Mrs. Brown, treasurer. In January 1945 Moose Jaw received their charter and were known as the Old Age Pensioners, Branch 5 Moose Jaw. The object of the club was to try to get together to make life less lonely for the elderly. The first officers elected for Branch 5 were Mr. E. Heath, president; Mrs. Ellis, first vice-president; Mr. Vaughn, secretary; Mrs. E. Foster, treasurer. Aims were to visit the sick at home and in the hospitals and to send cards to the sick and bereaved. A ladies auxiliary was formed to assist with fundraising projects. Four meetings a month were held in a small room on Main St. From 1954 to 1957 meetings were held in the I.O.D.E. room at the Y.M.C.A. With over 400 members in 1957 a larger hall was required, so the Odd Fellows Hall was rented for meetings from 1957 until 1964.

After the Old Age Pensioners approached several clubs in 1961, the Cosmos Club offered to sponsor them in their efforts to build a facility. After a meeting of the city, officers of the Old Age Pensioners, and Mr. Jack Dorfman, president of the Cosmos Club, the Pensioners agreed to turn over $11,000.00 to the Cosmos Club. The City of Moose Jaw provided the land to build, and in 1963 the Cosmos Centre opened. The Old Age Pensioners were given the use of the Centre.

In 1971 the name Old Age Pensioners changed to the Pensioners and Senior Citizens Organization of Saskatchewan, Branch 5, Moose Jaw. At a convention in Saskatoon in 1981 they joined with the New Horizons and became known as Saskatchewan Seniors Association Incorporated, Branch 5.

In 1984 Branch 5 had 59 members. It was the only charter branch left in the province. Officers were Violet Peeling, president; Agnes Goodnough, secretary; and Mrs. H. Braaten, treasurer.

On May 8, 1997 it was decided to disband Branch 5. Membership had declined to six active members. Mary Webber was president, Violet Peeling, secretary. Remaining funds were donated to the Moose Jaw Union Hospital and to the Provincial Saskatchewan Seniors Association Inc. All record books and material were donated to the Archives Dept. of Moose Jaw Public Library.
